| 20080302087 | Exhaust system monitoring methods and systems - A diagnostic system for an exhaust system including a catalyst and a post-catalyst oxygen sensor is provided. The system generally includes a fuel control module that commands fuel to transition from a rich condition to a lean condition and that commands fuel to transition from the lean condition to the rich condition. A first diagnostic module monitors the post-catalyst oxygen sensor during the transition from the rich condition to the lean condition. A second diagnostic module monitors the catalyst during the transition from the lean condition to the rich condition. | 12-11-2008 |
| 20100242933 | POST OXYGEN SENSOR PERFORMANCE DIAGNOSTIC WITH MINIMUM AIR FLOW - An engine control system includes an oxygen (O | 09-30-2010 |
| 20110106411 | SYSTEMS AND METHODS FOR DIAGNOSING OXYGEN SENSORS AND CATALYTIC CONVERTERS OF EXHAUST SYSTEMS - A diagnostic system for an engine includes a stage transition module and a control module. The stage transition module generates a command signal based on a fuel control signal. The command signal commands a fuel system of the engine to intrusively transition between rich and lean states during a diagnostic test that includes first, second, and third stages. The first, second, and third stages are defined based on transitions between the rich and lean states. The control module during the second and third stages detects: an error with a first oxygen sensor based on a comparison between the command signal and a first oxygen signal from the first oxygen sensor; an error with a second oxygen sensor based on a second oxygen signal from the second oxygen sensor; and an error with a catalytic converter based on the first and second oxygen signals and a manifold absolute pressure signal. | 05-05-2011 |

| 20090309422 | System and method for managing energy use in an electric vehicle - A method and system for using a secondary energy source with an electric or hybrid vehicle in a way that requires no interaction with the vehicle's on-board communications system or the vehicle's processors. The secondary energy source, which can be a battery pack or any energy storage device, can generally be charged at home or business using the 110 volt line. The energy from the secondary source can be metered into the system in a way that allows the primary battery state-of-charge to fluctuate normally. Most of the electrical energy propelling the vehicle can come from the secondary source. All of the regenerative energy from braking can go into the primary battery. A controller can control a regulator to regulate the amount of current flowing from the secondary source. | 12-17-2009 |

| 20110090147 | TOUCHLESS POINTING DEVICE - A touchless input device for a computer replaces a computer mouse and does not require physical contact between the user-operator and any part of the input device. The touchless input device uses multiple, linear near infrared, optical sensors and multiple near infrared light emitters working in a plane in space, all held inside a frame with an opening that defines the detection region. The device images the plane and processes the images to determine the presence, location and velocity of objects in the plane. The operator introduces an object, such as a finger, into the plane and moves the object in the plane to emulate the motion of a computer mouse across a desktop. Mouse buttons and other functions are emulated by unique motions in the plane. The device communicates these motions and events to the computer typically using a Universal Serial Bus. | 04-21-2011 |
